Story Highlights

TV viewers haven't seen the last of Black Canyon City crooner Frank Dimitri, whose lively rendition of "I've Got the World on a String" wowed the judges on "America's Got Talent."

An NBC spokeswoman confirms that Dimitri — billed simply as "Frank the Singer" on air — will make his second appearance on the program the week of June 29. That means the 74-year-old performer will either appear on Tuesday, July 22, or Wednesday, July 23. Both episodes start at 7 p.m. and air on Channel 12 (KPNX).

During his premiere appearance on Sunday's show, Dimitri charmed with a swinging, confident vocal performance. He earned standing ovations from judges Howie Mandel, Heidi Klum and Mel B, who described his voice as "so smooth and so sexy. I'm probably a little bit in love with you."

A YouTube video of Dimitri's performance is also catching fire, earning more than 497,000 views in less than a week.

According to his Facebook page, Dimitri is a member of Phoenix Union High School's class of 1958. In addition to Sinatra, he is a fan of such classic pop vocalists as Eydie Gorme, Buddy Greco and Nancy Wilson.
